The present invention claims priority as follows: U.S. patent application No. 62/379,275 filed 2016, 8, 25. The above-mentioned U.S. patent application is hereby incorporated by reference.

Technical Field

The present invention relates to a wireless communication technology. In particular, the present invention relates to device-driven power scaling in advanced wireless modem architectures.

Background

Today, wireless modems (wireless modems) for mobile devices are continually evolving to support higher data rates, improve spectral efficiency (spectral efficiency), and provide lower latency. Each new improvement increases processing requirements as well as power consumption. Although the capacity of batteries for powering mobile devices increases as technology advances, the rate of increase in battery capacity is very slow and maintaining battery life becomes a significant consideration in modern designs.

Many circuit techniques for meeting high throughput requirements do not scale (scale) power as throughput drops, so that in this case, a 90% data rate drop only reduces device power consumption by 10%. Thus, the efficiency of transmitting data (power per bit) is greatly reduced at lower data rates, and switching between low power and high power modes is non-instantaneous, although low power mode operation (e.g., dynamic voltage/frequency adjustment) is possible if lower throughput is predictable. The low latency requirement means that the wireless modem (alternatively referred to herein as a "modem") is required to respond very quickly to burst peaks in the data traffic in order to react to the information contained in the control channel, which limits many opportunities for power savings.

The above problems are better described using a simple example. For the third generation partnership project (3GPP) Long Term Evolution (LTE), a User Equipment (UE) modem needs to receive and decode a Physical Downlink Control Channel (PDCCH) at each Transmission Time Interval (TTI, equal to 1 ms). The PDCCH-enabled modem determines how much data the network has sent to the PDCCH during the individual TTIs. In the existing LTE standard, the present modem requires all internal circuitry to be prepared to handle a variable amount of data up to the highest possible downlink data rate, in each individual consecutive TTI, as supported by the performance class (capability class) of the present modem. For LTE class 4 devices, the maximum instantaneous data rate is 150 megabits per second. In many scenarios, the stably predictable maximum data rate never exceeds a level that is several orders of magnitude below the maximum instantaneous data rate supported by the UE. Unfortunately, current 3GPP standards limit modems to always being prepared to handle maximum data rates even when the known data rates are low, which prevents the modems from setting the modem circuits to a more energy efficient, lower peak processing state.

It is also contemplated that, in general, the circuit response time of a reconfigured lower performance modem will tend to be longer than the duration of the TTI used by the base station in which the base station schedules a variable amount of data for a particular UE. Given the speed of data rate change driven during a TTI, it is generally not possible to track circuit configuration changes used to reduce data consumption of the modem.

For voice calls, the modem may only need to process data at a speed of approximately 10 kilobits per second (kbps), which is 15000 times lower than the peak device processing performance. The ratio between predicted peak processing performance and device peak data rate for many modem use cases is even greater than high LTE device performance. Even in 5G technology, an increase in the imbalance between the predicted worst data rate and the peak data rate can be expected, where the peak data performance can reach 10 gigabits per second (Gbits/s), which is orders of magnitude greater than 6 (i.e., 1 million) times the typical 10 kilobits per second data rate required for voice communications.

The above constraints do not necessarily limit many popular internet applications that maintain a predictable low level of background data traffic and are designed to tolerate relatively long end-to-end delays in the transmission of larger amounts of data. In such a scenario, low latency and high instantaneous data rates are not required, and keeping the modem in a high alert state wastes battery power. By limiting the total length of time that the UE communicates with the network, the user experience is reduced, and ultimately, the operator revenue is reduced.

In the existing technology, a network distinctive technology, such as a Discontinuous Reception (DRX) and Discontinuous Transmission (DTX) technology, is used to reduce an effective duty cycle (duty cycle) to maintain power. The above technique necessarily increases the delay, but at the beginning of each reception cycle the modem must start at maximum power so that it is immediately ready to receive data at maximum rate if the control channel signalling valid data is present. In the existing art, provision is also made to reduce device operating power in response to certain events (e.g., increased temperature or insufficient battery power). In another approach, a device may selectively terminate communication if it detects that its power consumption exceeds a predetermined threshold. However, in general, the network controls all primary operating parameters that affect the power consumption of the modem. Since it is always desirable that the modem be able to operate at the maximum performance of the device class in which devices are registered in the network, there is only a limited range for the modem to effectively manage its own power consumption to maximize battery usage time.

Furthermore, in the highest performance wireless modem, heat dissipation (thermal) becomes an issue regardless of whether power is supplied by a battery. It is likely that in the future, many modems will only be able to provide maximum throughput for a limited time before internal temperature rise conditions exceed the need to maintain power usage at the operating temperature limit. If the mitigation strategy for the above problem is most effective, it should be device driven rather than network driven, since the network cannot reasonably know the thermal characteristics of every device on the market.

Detailed Description

Certain terms are used throughout the description and following claims to refer to particular components. As one skilled in the art will appreciate, manufacturers may refer to a component by different names. This specification and claims do not intend to distinguish between components that differ in name but not function. In the following description and in the claims, the terms "include" and "comprise" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to. Furthermore, the term "coupled" is intended to encompass any direct or indirect electrical connection. Thus, if a first device couples to a second device, that connection may be through a direct electrical connection, or through an indirect electrical connection via other devices and connections.

The following description is of the best mode contemplated for carrying out the present invention and is made for the purpose of describing the principles of the invention and not for the purpose of limiting the invention. It is to be understood that embodiments of the present invention may be implemented by software, hardware, firmware, or any combination thereof.

FIG. 1 is a schematic diagram of a network environment 100 described in accordance with an embodiment of the invention. Referring to fig. 1, a network environment 100 includes a radio modem 110 in wireless communication with a radio network node 160, wherein the radio network node 160 is part of a network 170. Wireless modem 110 may include one or more radio receivers (shown in fig. 1 as "receiver 112") capable of receiving wireless/radio frequency signals over a communication channel from one or more remote transmitters (shown in fig. 1 as "transmitter 162") of network node 160. Wireless modem 110 may also include one or more radio transmitters (shown in fig. 1 as "transmitter 114") capable of transmitting wireless/radio frequency signals over a communication channel to one or more receivers (shown in fig. 1 as "receiver 164") of network node 160. The portable wireless modem 110 may be powered by a power supply 150, wherein the power supply 150 may be a rechargeable battery. The wireless modem 110 may also include a signal processing subsystem 130, wherein the signal processing subsystem 130 includes an inner Receiver (RX)132, an outer Receiver (RX)134, and a Transmit (TX) path 136, wherein the inner Receiver (RX)132 demodulates and performs measurement operations on received signals, the outer Receiver (RX)134 performs decoding and error correction operations to distinguish desired signal portions from signal interference due to non-ideal characteristics of the communication channel, and the Transmit (TX) path 136 generates digital samples representing transmitted signals and data. The wireless modem 110 may also include a front end subsystem 120, wherein a portion of the front end subsystem 120 may be the receiver 112, the transmitter 114, and/or the signal processing subsystem 130 (depending on the actual circumstances of the internal architecture of the wireless modem 110). Front end subsystem 120 performs filtering and conversion of signals between digital (labeled "D" in fig. 1) and analog (labeled "a" in fig. 1) formats.

Wireless modem 110 may also include a control processing subsystem 140, wherein the control processing subsystem 140 manages the flow of data through wireless modem 110. The control processing subsystem 140 distinguishes signaling data from user data and processes radio network protocols. In modern modem designs, while specifying the maximum performance in the defined performance classes, front end subsystems 120, signal processing subsystem 130, and control processing subsystem 140 may each be designed with multiple operating power saving modes to reduce power consumption at the expense of performance parameters. Control processing subsystem 140 may include a power configuration manager 145 to track the power state of each subsystem.

Currently, the network may configure a period during which no data is sent to the wireless modem, thus allowing the modem to shut down the receive path (e.g., DRX) during that period to save power. In the above process, the modems are passive, although the signaling to the network's modems is allowed to indicate the prioritized DRX parameters. In a similar manner, when the modem has no content to send, it may turn off the transmit path (e.g., DTX) to save power. However, the case remains where, at the beginning of an active receive period, the data to be received is transmitted using any modulation or coding scheme that achieves the maximum performance class supportable by the modem. Assuming maximum throughput conditions apply, the modem needs to speculatively acquire the received data until the control channel has been decoded. Therefore, any power state changes that limit modem performance need to be deferred until after control channel decoding is complete. For example, but not limited to, the power state change may include adjusting a clock frequency, adjusting a supply voltage, and/or modifying a bias current to change a linearity specification in the transceiver component. Thus, additional power savings may be achieved when the network agrees to reduce modem performance in the event that the user does not require the modem to implement the highest performance.

In the inventive arrangements, the wireless modem may notify the network when the modem wishes to enter a power save state that degrades its performance. In the inventive arrangements, the network may inform the modem (which is operating under device classification performance) when improved performance is required. Fig. 5-7 provide examples of how the inventive arrangements can be applied to practical scenarios.

Fig. 2 is a diagram depicting control channel signaling in an LTE network. Referring to fig. 2, in the currently indicated LTE network, the first symbol of the transmission time interval is used for the control channel (PDCCH), which carries information to indicate which symbols and resources for receiving the modem in the subsequent transmission of shared channel data (PDSCH) and to indicate which modulation scheme is used. Since it takes time to process the control channel information, the PDSCH receiving operation is started until the information has been decoded. Therefore, the modem is required to maintain all resources in the standby state to process data at the maximum rate.

FIG. 3 is a diagram depicting power requirements versus performance for different performance states (capability states). As shown in fig. 3, high state performance in the modem corresponds to high data rates per carrier and requires high power requirements. Considering the modems with performance states shown in fig. 3 (e.g., performance state a, performance state B, and peak performance state in ascending order), in the current 3GPP standard, the modems need to use the peak performance state. Therefore, the power consumption of the modem may be increased more than necessary.

FIG. 4 is a diagram illustrating switching between performance states to reduce power consumption, according to an embodiment of the invention. Referring to fig. 4, in the inventive arrangements, the modem may negotiate with the network to enter a temporary low performance state (e.g., performance state a), and the network may maintain the data rate within the agreed limits of the low performance state. Additionally, as a larger amount of data comes for the modem, the network may command the modem to increase its performance state (e.g., performance state B or peak performance state) before the network sends data to the modem at a high data rate. Further, when data transmission at the high data rate is complete, the modem may request to enter a low performance state (e.g., performance state B) to conserve power. Advantageously, this allows the modem to more efficiently use power resources when peak performance is not needed to meet application requirements.

In the solution of the present invention, different types of functions supported by an LTE mobile device or UE, such as video, email, and voice, can be mapped to different power states. For example, since typically an email function is associated with a low data rate, random arrival time, and long delay characteristics, the function may map to a low performance state. In addition, since a voice function is typically associated with low data rates, predictable arrival times, and short delay characteristics, the function may be mapped to a neutral performance state. Furthermore, since video functions are typically associated with high data rates, random arrival times, and medium delay characteristics, the functions may be mapped to high performance states.

For operation at low data rates, the modem may implement a temporary performance state in which the modem may save power by reducing the internal clock frequency as well as the core voltage. However, in this temporary performance state, the reduced processing performance may render the modem incapable of processing video level data traffic. Even though a modem belongs to a class 6 performance device when it operates at high core voltage and clock frequency, it is satisfactory as a LTE class 1 device. To minimize power consumption, the modem may operate in long DRX cycles or idle but wake up periodically for email, and additionally, when voice is activated, the modem may switch to short DRX cycles in order to meet the latency reduction requirements. Typically, the rate of change of the temporary performance state exceeds 200 ms, which is much slower than the scheduling rate indicated by one TTI (1 ms).

When a user or network activates the video function, the modem may increase the core voltage and clock frequency, then signal a temporary performance state change to the network, which then communicates with the modem as a class 6 device. When video activity terminates, the modem signals another temporary performance state transition to the network and, once the network acknowledges, resumes class 1 communication and the modem returns to a low performance state to conserve power. Typically, the rate of change of the temporary performance state exceeds 200 ms, which is much slower than the scheduling rate indicated by one TTI (1 ms).

In an embodiment of the present invention, the temporary change of performance state in the modem is accomplished under existing standards by deregistering and re-registering the modem each time a performance change is required. However, there are many limitations to this. First, the process involves a disconnection and the network then does not know whether the modem registered as class 1 can be class 6 or not. Then, the low power temporary performance state may require an undefined intermediate device class that has a performance subset of one performance state, rather than a superset of another performance state. This may result in additional signaling overhead for the network since the steps of the partial network authentication and registration process need to be repeated unnecessarily.

In an embodiment of the invention, additional signaling is introduced for the modem to negotiate a temporary change in maximum device performance with the network. By way of example and not limitation, changes in maximum device performance may relate to peak data rate changes, total allowed bandwidth to be handled by the modem, number of active carriers, maximum resource block allocation, or highest modulation coding scheme. This allows the modem to remain registered in the highest class while optimizing power consumption in the application type required by the current modem application. This causes a rapid change in the modem processing requirements since in the previous case the temporary performance state transition rate is responsive to changes in how the modem is used and will be at least one or two orders of magnitude slower than the control information reception rate.

5-7 show illustrative and non-limiting examples of different types of state changes. The acceptance of the state change request may be selected or forced according to a signaling protocol.

Fig. 5 is a diagram depicting an exemplary process 500 for modem initial performance increase, in accordance with an embodiment of the invention. Process 500 may be implemented using network environment 100 or process 500 may be implemented using any network, including wireless modems and wireless networks, to achieve the various features and/or aspects of the present invention. More specifically, process 500 may involve a modem-initiated capability addition (modem-initiated capability addition). Process 500 may include one or more operations, actions, or functions represented by one or

more blocks

510, 520, 530, 540, 550, 560, 570, and 580. Although described using discrete blocks, the various blocks of process 500 may be partitioned into additional blocks, combined into fewer blocks, or eliminated, depending on the actual needs. Process 500 may be implemented in whole or in part by each of wireless modem 110 and wireless network node 160 described above, or each of communication device 810 and network device 820 described below. For purposes of description only and not to limit the scope of protection, process 500 is described below in conjunction with network environment 100. Process 500 begins at block 510.

At block 550, the wireless modem 110 may determine whether a positive reply (e.g., an acknowledgement message) has been received from the wireless network node 160. In the event that a confirmation message is received from radio network node 160, process 500 proceeds from block 550 to block 560, the modem initial state change is successful, and radio modem 110 may remain in a high performance state. Process 500 may also proceed from block 550 to block 530 where the status change request continues to be issued/sent to radio network node 160 for radio modem 110. Otherwise, process 500 may proceed from block 550 to block 570 in the event that an acknowledgement message is not received (e.g., an acknowledgement message is not received upon expiration or expiration of a timer) or a negative reply message is received (e.g., a rejection message).

At block 570, wireless modem 110 may return from the high performance state to the low performance state, and process 500 may proceed from block 570 to block 580 where the modem initial state change was unsuccessful.

Fig. 6 is an exemplary process 600 for modem initial performance reduction, described in accordance with an embodiment of the present invention. Process 600 may be implemented using network environment 100 or using any network including wireless modems and wireless networks to achieve the various features and/or aspects of the present invention. More specifically, process 600 may be reduced with respect to modem initial performance. Process 600 may include one or more operations, actions, or functions represented by one or more of

blocks

610, 620, 630, 640, 650, 660, and 670. Although described using discrete blocks, the various blocks of process 600 may be partitioned into additional blocks, combined into fewer blocks, or eliminated, depending on the actual needs.

For purposes of description only and not to limit the scope of protection, process 600 is described below in conjunction with network environment 100. Process 600 may begin at block 610.

At block 610, the wireless modem 110 may determine to reduce its performance (e.g., from a high performance state to a low performance state). Process 600 may proceed from block 610 to block 620.

In block 620, the wireless modem 110 may issue or send a state change request to the wireless network node 160. Process 600 may proceed from block 620 to block 630.

At block 630, the wireless modem 110 may wait for an acknowledgement message from the wireless network node 160. Process 600 may proceed from block 630 to block 640.

At block 640, the wireless modem 110 may determine whether a positive reply (e.g., an acknowledgement message) has been received from the wireless network node 160. In the event that an acknowledgment message is received from radio network node 160, process 600 proceeds from block 640 to block 650.

At block 650, the wireless modem 110 may activate a low performance state and the process 600 may proceed from block 650 to block 660 with the modem initial change successful.

Otherwise, process 600 may proceed from block 640 to block 670 in the event that an acknowledgement message is not received (e.g., an acknowledgement message is not received when the timer times out or expires) or a negative reply message is received (e.g., a reject message), the modem initial change is not successful. Alternatively, process 600 may also proceed from block 640 to block 620, where for wireless modem 110, a status change request is continuously issued/sent to wireless network node 160.

Fig. 7 is a diagram depicting an example process 700 for initial performance changes of a network, according to an embodiment of the invention. Process 700 may be implemented using network environment 100 or any network including wireless modems and wireless networks to achieve the various features and/or aspects of the present invention. More specifically, process 700 may initially change performance with respect to the network. Process 700 may include one or more operations, actions, or functions represented by one or more of

blocks

710, 720, 730, 740, 750, 760, and 770. Although described using discrete blocks, the various blocks of process 700 may be partitioned into additional blocks, combined into fewer blocks, or eliminated, depending on the actual needs. Process 700 may be implemented in whole or in part by each of wireless modem 110 and wireless network node 160 described above, or each of communication device 810 and network device 820 described below. For purposes of description only and not to limit the scope of protection, process 700 is described below in conjunction with network environment 100. Process 700 may begin at block 710.

At block 710, the radio network node 160 may determine to change the modem performance of the wireless modem 110. Process 700 may proceed from block 710 to block 720.

At block 720, the radio network node 160 may issue or send a status change request to the radio modem 110. Process 700 may proceed from block 720 to block 730.

At block 730, the wireless modem 110 may determine whether to receive the request. In the event of a positive determination (e.g., acceptance), process 700 may proceed from block 730 to block 740. Otherwise, in the event of a negative determination (e.g., denial), process 700 may proceed from block 730 to block 770, where the network initial state change is unsuccessful.

At block 740, the wireless modem 110 may activate a new performance state, which is a lower or higher state than the current performance state. Process 700 proceeds from block 740 to block 750.

The wireless modem 110 may send an acknowledgement message to the wireless network node 160 to indicate and acknowledge the state change at block 750, and the process 700 may proceed from block 750 to block 760 where the network initial state change was successful.

In aspects of the invention, a thermal sensing module in the modem may be utilized to monitor the temperature of one or more system elements of the modem. If the temperature rises above a predetermined threshold (e.g., perhaps due to continued operation at or near peak throughput), the modem begins to switch to a low temporary performance state for a period of time, allowing its temperature to return to a safe operating level. In this case, the modem may perform a modem initial performance reduction process similar to that shown in fig. 6. Alternatively, in security considerations, the modem may automatically switch to a low performance state without getting an acknowledgement message from the network.

In the solution of the invention, the modem may start to switch to the lowest temporary performance state when the user of the modem selects a battery conservation mode (batttersize mode) or when the battery sensing indicates that the remaining battery capacity falls below a threshold value, and leave this state only in response to the user's request. In this case, the modem may perform a modem initial performance reduction process similar to that of fig. 6. Alternatively, the modem may automatically switch to a low performance state without getting an acknowledgement message from the network.

In an embodiment, a modem with band or mode selection may prefer the band and mode that maximizes transceiver performance. In an embodiment, the modem may adjust its temporary performance state to match the needs of the active application in the application processor.

In an embodiment, when the modem is an LTE modem, the modem may signal its priority temporary performance state to the LTE network by extending the range listed in the powerPrefIndication in the UEAssistanceInformation message. Information regarding the priority temporary performance state may also be signaled in the AS context field of the handover preparation information message so that the temporary performance state is passed to the new eNB during handover. Next, the capability of each state is defined by inserting a capability set list of UE-EUTRA capability indications using powerPrefIndication as an index. The network or modem and the network initial temporary performance state transition require new signaling to confirm the temporary performance state transition. An additional entry in the UE-EUTRA capability field is required to indicate whether the modem supports the above capabilities.

The following description is with respect to the operation, functionality, and performance of the communication device 810.

In an embodiment, the communication device 810 may be a wireless modem with time-varying peak processing performance during active modem operation. That is, the communication device 810 may have multiple sets of temporary performance states at zero to peak performance. The currently selected temporary performance state of the communication device 810 may be a result of negotiation with a network (e.g., a network device 820 that is a wireless network node of the network, such as an eNB of an LTE network). The duration of the selected temporary performance state may exceed the period of control information used by the network that dynamically schedules data transmissions with the communication device 810. Data transmission between the network (e.g., network device 820) and communication device 810 may be restricted according to the currently selected temporary performance state.

In an embodiment, the processor 812 of the communication device 810 may send a request to a network (e.g., network device 820) through the transceiver 816 for a temporary performance state transition, such that the processor 812 may perform operations of the communication device 810 to enter a priority temporary performance state to reduce power consumption or increase its performance. Upon receiving an acknowledgement message or a permission message from the network, the processor 812 may perform operations for the communication device 810 to enter a desired state change (e.g., by adjusting one or more operating parameters of the communication device 810).

In an embodiment, the processor 812 may change the temporary performance and power state of the communication device 810 in response to a request or indication by the network.

In an embodiment, the processor 812 may notify the network (e.g., by signaling the network) before the processor 812 changes the temporary performance state of the communication device 810.

In an embodiment, the processor 812 may negotiate a priority temporary performance state with the network. Further, when the processor 812 decides to change the temporary performance state of the communication device 810, the processor 812 may notify the network.

In this case, the processor 812 may manage its own power states to control power consumption of the communication device 810. Further, processor 812 may notify one or more other network devices (e.g., other radio modems and/or UEs) of any changes in the temporary performance state of communication device 810.

In an embodiment, the processor 812 determines which of a set of temporary performance states is the preferred temporary performance state for optimal power consumption by taking advantage of the system requirements of the communication device 810, wherein the determination is made within the system requirements limits of the communication device 810.

Once necessary, the processor 812 may transition the temporary performance state of the communication device 810 from the current performance state to a low performance state. For example, processor 812 may perform a modem initial performance reduction process similar to that shown in fig. 6. Alternatively, the processor 812 may automatically switch to a low performance state before or without retrieving an acknowledgement message from the network.

In an embodiment, the communication device 810 may also include one or more sensors (not shown) that may sense environmental parameters (e.g., temperature, humidity, barometric pressure, etc.). In this case, processor 812 may receive the device thermal status by receiving sensor data from one or more sensors located in communication device 810. Alternatively, the processor 812 may determine the device thermal state based on the most recent and current device operating parameters and the thermal power model.

In an embodiment, by utilizing the known amount of remaining power, the processor 812 may determine a priority temporary performance state among the set of temporary performance states, which may maximize remaining battery usage time.

In an embodiment, processor 812 may define a set of temporary performance states available by utilizing user-defined settings. For example, the user may enter user-defined settings that cause temporary performance state C to be removed from the set of temporary performance states A, B, C. Thus, the states may be temporary performance states A and B.

In an embodiment, the processor 812 may select a network mode and/or frequency band to minimize power consumption of the communication device 810 by utilizing known available network modes and/or frequency bands.

In an embodiment, the processor 812 may include a power configuration management module 815 in communication with the wireless network through the transceiver 816 to handle transitions between performance states and power states. The power configuration management module 815 may be an embodiment of the power configuration manager 145 of the radio modem 110. In an embodiment, the processor 822 of the network device 820 may include a power configuration management module 825 in communication with the power configuration management module 815 through the

transceivers

826, 816 to determine which temporary performance state to select from the set of temporary performance states for the communication device 810. Each of the power

configuration management modules

815, 825 may be implemented as hardware (e.g., one or more circuits), software, or a combination of both.

In an embodiment, processor 812 may log off from the network (e.g., network device 820) and then re-register with a different temporary performance state than the proposed selected temporary performance state.

In an embodiment, the set of temporary performance states is associated with one or more aspects of the communication device 810, such as, but not limited to: a peak/maximum Receive (RX) data rate, a peak/maximum Transmit (TX) data rate, an aggregate RX bandwidth, an aggregate TX bandwidth, a maximum number of active RX bearers, a maximum number of active TX bearers, a total allowed bandwidth to be processed by communication device 810, a maximum resource block allocation, a highest modulation and coding scheme, a set of used frequency bands, a number of active RX antennas, a number of active TX antennas, a maximum RX multiple-input multiple-output (MIMO) order, a maximum TX MIMO order, a set of traffic required by an application processor (e.g., processor 812 or another processor) of communication device 810, a set of Radio Access Technologies (RATs) used by transceiver 816 to wirelessly transceive data, and one or more processing requirements of processor 812 and/or application processor.

In an embodiment, the processor 812 may select the temporary performance state by affecting a change in a configuration frequency of each internal clock signal. Alternatively, the processor 812 may select the temporary performance state by affecting a change in the configuration voltage of each system power supply. Alternatively, the processor 812 may select the temporary performance state by a change that affects the amount of resources currently active.
